SCP-4211 host's typically have a dark blue discolouration to their iris's and pupils, the hosts eyes with also emmit a light between 130 and 250 lumen and this can happen to any human, Though SCP-4211 almost always manifests itself in Dr. Harvid, who will now be referred to as SCP-4211-2.
When SCP-4211 possesses SCP-4211-2 it can control minor body activities but can’t do much as SCP-4211-2 remains almost completely in control, While possessing SCP-4211-2 talks to him mentally and when foundation staff talks to SCP-4211 it is able to talk through SCP-4211-2’s body.
